has announced its first laser diode modulator (LDM), the SP8110.
Using ripple cancellation to extend bandwidth improves the frequency response of shunt diode modulators. The advantage of this device over previous AM modulator designs is that the current drive required to achieve a particular modulation is constant over a wider bandwidth.
